(30) What is the meaning of the statement that after a hundred and fifty days the water began to abate? (#Ge 8:3). We must here inquire whether those hundred and fifty days, during which the water was abating, are to be distinguished from the four months, or whether they have a reference to the days previously mentioned, during which the deluge went on unceasingly, as still increasing.
(31) Why does he say, “The ark settled in the seventh month on the seven and twentieth day of the month?” (#Ge 8:4). It is reasonable here to consider how the beginning of the deluge commences in the seventh month, on the twenty-seventh day of the month, and how the diminution, when the ark rested on the top of the mountains, again took place in the seventh month and on the twenty-seventh day of the month; therefore we must say, that there is here an homonymy of months and days, for the beginning of the flood took place in the seventh month, beginning at the birthday of the just man, near the time of the vernal equinox, and its diminution took place in the seventh month, beginning from the highest point of the flood at the autumnal equinox, since the two equinoxes are separated from one another by seven months, having an interval of five months between them. For the seventh month of the equinox is also by its virtue the first month, because the creation of the world took place in it, on account of the abundance of all things at that season. And, in like manner, the seventh month of the autumnal equinox, which, according to time, is the first in dignity, having its principle of that number seven derived from the air; therefore, the deluge took place in the seventh month, not according to time but according to nature, having for its principle and commencement the spring season.
